(the "Company") announces today that it has priced the offering of €400,000,000 aggregate principal amount of its senior notes due 2023 at a coupon of 6.375% per annum. The offering was upsized from the €300,000,000 amount announced on April 9. The issuance of the notes, which is subject to customary conditions, is expected to close on 19 April 2018.
